Hi,
What code did you use to add the module ? Without knowing your code, I can't say what you did wrong.
I would personnally do it like that:
<?php
$moduleHelper = hikashop_get('helper.module');
$modules = $moduleHelper->setModuleData(array(XX, YY, ZZ));
if(!empty ($modules) && is_array($modules)) {
jimport('joomla.application.module.helper');
foreach($modules as $module) {
echo JModuleHelper::renderModule($module);
}
}
?>
where XX, YY and ZZ are ids of the modules (one for each language). The setModuleData would automatically filter out the modules based on the current language and the associated language in each module and then the renderModule function would display the remaining modules.
That's similar code we use for the "Modules under the product page" setting of the HikaShop configuration.
